A simple mod that lets you toggle the visibility of item frames!
Just crouch and right-click on an item frame while it holds an item, and the frame will become invisible.
It’s server-side only, so it doesn’t require installation on client.
Some examples:

Some vanilla Items...

With Tacz mod...
I made this because I wanted to place the Tacz guns on the wall in a nice and visually appealing way.
You can use this mod in modpacks, play with friends, or anywhere you want!
